Since people with first hand experience in race critical and life on the line bombing downhill and remote trail environments love using my lights, then if you live in the SF Bay area, get in touch to arrange a test ride.
@ttoshi, thx for spreading the word about the light.
Joan Dietchman had awesome night time speeds this past weekend at the Furnace Creek 508, and four other racers there also found a special advantage with my lights, further affirming that these lights really do give bikers something special on the road versus any other optical approach available. They know that its not only about making lumens, its what color are they and where do you put them?
Naysayers are one of the many chuckholes that come with an inventors' and innovators' turf.
Its curious seeing people expound on far reaching assumptions, yet not contact me directly for simples answers. The amusing speculations and "must be" assertions take conventional wisdom to extremes. These leave out needs of a viable commercial product, nor consider non-amortized thousands already invested in de$ign and tooling. Interesting that no one commented on the built in high power charging circuit, essential for recharging higher power internal cells.
Cool Polymer is awesome stuff. Yes it does extude directionally, and requires a particular touch to machine it without chipping or shattering. A $400. ingot + 80+ hours got me the CNC'ed test heatsinks that I made prototypes and did thermal measurements from.
The antique motorcycle solution would be a DC to DC regulator taken from the output of another device made by an electrical specialites company in place of the antique generator. The project needed more time and $$ than the customer's schedule and budget would allow.
Funny, also, to see an old troll still at it, after I needed to block him or he was removed from harrassing other lists. Certainly the monitors should address his use of demeaning language and slanderous portrayal at me.
Since most of the postings raise topics that the Kickstarter page covers, please read it before posting further.
Best way to see what a few years and a ton of money went into developing, is to place an order.
The demands of launching a startup take up more time than there are hours on the clock. I did want to respond to the thread, and thank you for the bandwidth and exposure.
This will be my only posting here til my brake/taillight is ready to launch in a few months. Please send further tech questions through the Kickstarter project site and I'll answer promptly, and please do keep spreading word about my project.
My advice, if you don't want to do that, from Mark Twain,
"Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great."

Once again, if you care to ask questions directly instead of this behind my back slander fest as if I came out and proved that Jesus wasn't divinely conceived, then you can ask them on my Kickstarter, by clicking on the light blue colored box on the bottom of the project description titled "Ask a question."
This is contrary to Esko's mistaken claim that you have to place an order before you can ask a question.
Applesnail's video clips and erroneous interpretation got me curious. If you are the guy with antique Harley's, your sour grapes posting shows that I should not trust giving you lighting support on future events. Considering the strength of the direct introduction I was given to you, you really ought to know better than to claim against the first hand judgement of a guy who zipped around at night on a motorcycle with his only lighting coming from my light clamped to his handlebar.
The problem with those frame clips is omitting the source of the images. Frame capture of a 60FPS compact videocam in motion under high frequency road vibration with rapid image stabilization and exposure metering correction has obvious limits. I'm not into posting knowingly deceiving stationary shot from a high resolution camera on a tripod. The frame captures shows are misleading, whether that was done knowingly or not.
But I would expect a higher degree of common knowledge on this list than to not question the type of equipment and camera settings used for any night photography taken. I'll hand over a live light for the side by side lighting shootouts on MTBR. For reference, in their 2006 shootout, my setup at that point in LED lighting development was equal to the best of the test at any price, and couldn't be included because it wasn't a commercially available light. Those lights were the stone age compared to where I am now. While the rest of the industry continues to build the same basic light, based on the same conventional wisdom.
Contrary to Esko's attempt to stop any of you from asking questions to me through Kickstarter, anyone can ask a question on Kickstarter without needing to place an order.

The very few people who get prototypes are on rigid NDA agreements, including detailed burden of proof clauses that cover the Lawrence Livermore case criteria, and have demonstrated specific need to know. Anyone is welcome to buy a light and reverse engineer for their own personal and private use. The anxious enthusiasm to get wholesale quantities of my lights based on demos I gave at Interbike to well known and long established major bike equipment distributors states the high value my lights will have on the market.
For anyone studying usable visibilty and optical design, the almighty total lumen count is a false god. It seems that Candlepower Forums lives in a vacuum of self declared false authority to anoint or excommunicate according to what conforms to only your approved range of conventional wisdom. Since there is little about my lights that follows conventional wisdom, I don't expect much acceptance of my ideas on this list.
A better use of your collective braintrust would be to devise a usable visibility measurement which would provide accurate indication of the real usable visibility that a bicycle light provides. End lumens, beam lumens, and field lumens would be a start. A field lumen measure of the beam lumens on a German STVo type target might be a start.
Several people who I steered this thread to found the general attitude entertaining. The clearest portrayal was, "Wow...some of these guys need attitude adjustments...yikes!"
Now that I've responded to those single frame screen captures, and described where to ask a direct question through Kickstarter without making a purchase, I really am out of here. Either write me there, contact me privately, or schedule a night ride where I'll set you up with a light to try out yourself.

I don't have a big problem with the false-color graph - it's more than Ph*enix or Filyps AktyveR!te are offering at the moment.... However, it made me wonder which of Barry's claims about superior lighting quality are justified - compared NOT to his cycling buddies' repackaged flashlight beams, but to vehicle beams. And I'm not even talking about complicated, fancy stuff like this... heck a numerically accurate simulation as opposed to a too small to see color graph would work too.

I'm sad to see someone assuming so many things about me. The last time I was on a motorcycle, I was about six. I know quite a bit about photography and videos of flashlight output. However, you are correct: I should have clarified why I grabbed stills from your video:Applesnail's video clips and erroneous interpretation got me curious. If you are the guy with antique Harley's, your sour grapes posting shows that I should not trust giving you lighting support on future events.

Wrong. Unfortunately, there are several severely challenged experts who perpetuate those myths on the interwebs.However, AFAIK the maximum power allowed in the oldish StVZO regulations is 2,4 watts in a 6 volts system, and 5 watts in a 12 volts systems. Sure enough, there are more powerful lights that have the approval. As far as I know, they shouldn't have been approved though.
Wrong. Unfortunately, there are several severely challenged experts who perpetuate those myths on the interwebs. Unlike them, you might understand a friendly hint like 'One needs to read the entirety of a regulation in order to be able to correctly interpret it.' It's just laughable when someone's perception clashes with reality (factual governmental testing and approval, in this case), and he then insists on being right, starts behaving like a four-year old, and resorting to wild assumptions.
Good job, Esko, I thank you, and please don't take being "differently informed" (formerly called: wrong) personally. You did exactly what I would expect from real experts and anyone interested in learning the truth. Was it hard? No. Did it take some effort? Yes, but you'll remember what you found out, and if you had a website containing some erroneous information, you would simply edit it.
Further technical details are described in a number of "TA" regulations via paragraph 22a StVZO, TA #1 and TA #23 among them. Taiwanese manufacturers seem to be more familiar with these than Americans, and that's fine with me, no need to adhere to foreign standards if you have a better beam ... and succeed in convincing prospective customers that you really do.
Concerning the barrybeams lamp, I see little reason to discuss its battery power supply along some foreign administration's ideas.As far as I have read, it is TA 4 that supposedly contains the information about those power limits.
